Odor control device

Abstract

An odor control device for use with an air passage of a main heating and/or air conditioning system having a blower. The device has a body with an air flow chamber therein, a panel secured to the body and having an air inlet port for admitting air into the chamber, a rotatable plate mounted on the panel, and a container for odor conditioning material mounted on the rotatable plate and preferably held thereon by a magnetic bar attached to the plate and attracting a perforated metal plate in the container, thereby permitting the container to be easily removed from the plate and attached thereto. The panel and plates have communicating arcuate inlet and outlet passages to permit the air to pass from the chamber in the body to the container and thence to the conduit of the main system. The panel contains a main air intake port for the device, and an opening is provided in the body for communicating directly with the main system conduit, and thermostatically controlled shutters control the intake and last mentioned opening.

I claim: 
     
       1. An odor control device for use with an air passage of a main system having a blower therein: comprising a body having a chamber, a panel secured to said body and having an air inlet port for admitting air to said chamber, a rotatable plate mounted on said panel, a container for odor conditioning material mounted over and rotatable with said rotatable plate, said panel and plate having a first pair of openings forming a variable air flow passage from said chamber to said container, and a second pair of openings forming a variable air flow passage from said container into the air passage of the system, the effective size of said first and second openings being varied by the rotation of said plate on said panel, a partition disposed between said first and second pairs of openings and between said plate and container for directing air flow into said container, and means for detachably securing said container over the first and second openings in said plate and panel. 
     
     
       2. An odor control device as defined in claim 1 in which an opening is provided in said body communicating directly with the passage of the main system and a thermostatically controlled valve controls the size of said opening. 
     
     
       3. An odor control device as defined in claim 1 in which a dial is provided between said panel and rotatable plate and said plate is rotated by the rotation of said container. 
     
     
       4. An odor control device as defined in claim 1 in which an opening connects said chamber with said main system and shutters control said opening and said air inlet port, and a thermostatic element connected to both of said shutters controls said shutters in response to variations in the temperature of the air passing through said chamber. 
     
     
       5. An odor control device as defined in claim 1 in which said container has a magnetic attractable, perforated plate across the opening thereof, and said means for detachably securing said container includes a bar magnet secured to said rotatable plate and forming said partition between said first and second pairs of openings so that the air passing through the device is directed through the perforated plate in said container where the air absorbs the odor neutralizing material. 
     
     
       6. An odor control device as defined in claim 5 in which an opening is provided in said body communicating directly with the passage of the main system and a thermostatically controlled valve controls the size of said opening. 
     
     
       7. An odor control device as defined in claim 5 in which a thermostatically controlled valve controls the flow of air through said air inlet port. 
     
     
       8. An odor control device as defined in claim 5 in which an opening connects said chamber with said main system and shutters control said opening and said air inlet port, and a thermostatic element connected to both of said shutters controls said shutters in response to variations in the temperature of the air passing through said chamber. 
     
     
       9. An odor control device as defined in claim 1 in which said dial has off and on positions and a switch connected to the controls of the main blower system may control said blower independently of the controls on the main system. 
     
     
       10. An odor control device as defined in claim 9 in which a means is attached to said rotatable plate for operating said switch. 
     
     
       11. An odor control device as defined in claim 10 which a means is provided for manually controlling said switch separately from said rotatable plate.
